FRISCO -- Big 12 commissioner Bob Bowlsby said the conference will continue to withhold revenue from Baylor as the verification process continues into how Baylor has made institutional changes following its years-long sexual assault scandal.

Bowlsby stated that Baylor's leadership group of president Linda Livingstone, athletic director Mack Rhoades and head football coach Matt Rhule have been as cooperative as the Big 12 could hope. Bowlsby does not expect the investigation to conclude before the season begins.

It is obviously a very complex situation, and because of the lawsuits, it is -- it will have some effect on the time frame of our verification process, but we are moving forward with it," Bowlsby said at Big 12 media day. "We continue to withhold the 25 percent of their revenue distribution, and we'll continue to do that as long as this is a pending matter. ... We could not have had any better cooperation and any better engagement from the president, the athletic director, the head football coach, and general counsel and anybody else we've dealt with down there.

"They are working very hard to get it right."

The Big 12 announced in February it would withhold 25 percent of the school's share of conference revenue pending the outcome of an independent review of Baylor's athletic procedures and university governance.

Bowlsby declined to comment on the NCAA's investigation into how Baylor handled allegations of sexual assault against football players, saying the Big 12 is not involved in that investigation.
